in thread Forking Clients

The lexical variable $pid is evaluated and the result is then discarded. The variable is not tie-d to anything, so there can be no side effect. Don't you see a warning from this (although you don't use warnings; in your sample code)? All output from the $connection->rpc() function call is assigned to @resp. What's the point of having $pid in the statement? A typo or a thinko is strongly suggested.
>perl -wMstrict -le "my $pid = 'foo'; my @resp = qw{ a b c }; sub S { return qw{ FOO bar quux } } $pid, @resp = S(); print qq{$pid @resp}; " Useless use of private variable in void context at -e line 1. foo FOO bar quux

    I added the $pid part last second, it should have parens around the two variables I will fix it. I didn't really pay attention to it, I fixed the OP Thanks.
